SPECIFICATION forming part of Letters Patent No. 696,756, dated April 1,1902.

Application filed November 6,1901. Serial No. 81,355. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM RUNDonIsT, a citizen of the United States,residing at Elgin, in the county of Kane and State of Illinois, haveinvented certain new and useful'Improvements in J ewel-Setting Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as willenable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in watchmakers machines, moreespecially for It has for its objects, among other things, to providefor automatically forming the settings for the jewels and for securingsaid jewels therein, to facilitate operation, to promote efficiency, andto generally improve the utility of the invention.

It consists of the sundry combinations of parts, including their generalconstruction and arrangement,substantiallyas hereinafter more fullydisclosed and specifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure 1 is a side elevation. Fig. 2 is a sectionalelevation of the machine carrier or head, taken on the line to w of Fig.3. Fig. 3 is an enlarged sectional view taken at right angles to theplane of the last-referred-to view, taken on the linezmcof Fig.2. Fig. 4is an enlarged section showing more particularly the cutter for severingthe wire or stock, taken on the line yy of Fig. 5. Fig. 5 is a similarsection taken at right angles to the plane of the last-referred-tosection on the line .2 of Fig. 4. Fig. 6 is a detailed plan view of thedog forming part of the cutter-actuating mechanism for regulating ordetermining the movement of the cutter. Fig. 7 is also a detailed viewshowing said dog and a gearwheel in ooaotion. Figs. 8, 9, 10, and 11 aredetached views of the jewel-feeding device. Figs. Hand 13 are enlargeddetail views showing more fully the delievery end of thejewelfeedingdevice. Figs. 14 and 15 are detailed views of the burnisher. Fig. .16 isan enlarged detailed-view of an additional cutter. Fig. 17 is a likeView of the drill or reamer. Fig. 18 is a longitudinal section takenthrough the c0upling-bar, between the tool'carrying spindles and thecam-actuated lever therefor, on the line b I) of Fig. 2.

Latitude is allowed herein as to details, as they may be changed orvaried at will without departing from the spirit of my invention and thesame remain intact and yet be protected.

In carrying out my invention Imount upon a suitable support or framework1 a tool-carrier 2, having, preferably, a dovetailed sliding connection,as at 1 Said carrier or head, unlike the corresponding part asheretofore employed in this class of machines, slides horizontallyopposite the stock delivering or feeding device or chuck in performingthe several operations of treating the stock and securing the jewelstherein, as more fully disclosed presently. Said carrier or head ispreferably constructed, as shown, having forward and rear transversevertical portions 1 1 each provided with a nu mber of holes 1, those inoneportion alining those in the other portion, and within these holesare arranged spindles 2 carrying the respective tools employed in thisclass of machines. Said spindles are each fitted with orhave clampedthereon asplit collar 3 just inside of the rear transverse portion 1having a bifurcated lower end, as at 3, receiving a rod or guide 4,fixed to said rear transverse portion and projecting forward a distanceor being of a length corresponding to the movement of the spindles, saidcollars having their bifurcated portions riding upon said rods or guidesto prevent axial movement or turning of said spindles. Said spindleshave applied thereto or are encompassed for a portion of the lengththereof by springs 5, one end of each being secured to a spindle and theopposite end bearing against a transverse portion of the carrier or head2 to cause said spindles to respond automatically and promptly under theaction of their common actuating-lever mechanism,as presently seen. Thetension of said springs can be readily adjusted or stressed by suitablymanipulating nuts 5, applied to said spindles outside of said reartransverse portion of the carrier or head. The rear end of said spindlesare provided with spherical or globular-like enlargements or terminals5", and a coupling or head 6, having a cylindric socket 6, with alongitudinal slot 6 through its forward side to successively receivesaid spherical enlargements or terminals, is carried by and flexibly orpivotally connected to the upper end of a lever 7, suitably fulcrumed inthe frame or support 1. Said coupling or head has both its socket andslot opening out through both its ends to permit the insertion of saidspherical enlargements or terminals into said socket in effectingconnection between said coupling and the spindles, also to allow thepassage of said terminals or enlargements through said socket, to permitthe withdrawal of said enlargements or terminals as the carriage isintermittently moved transversely or at right angles thereto in bringingthe several tools in action.

A cam 8, secured upon a shaft 9, journaled and supported in the frame 1and suitably driven, actuates the lever 7, imparting a reciprocatingmotion thereto, the lower end of said lever or a roll 7 thereon engaginga tortuous groove 8 of said cam, said groove alternating back and forthfrom right to left, with its more extended arms traversing thecircumference of the cam in lines parallel with the sides thereof andits shorter arms connecting the first-named arms at their endsangularly, not as abruptly, however, as a right angle, as disclosed inFig. 2. Said toolcarrier itself is operated or moved intermittently, asabove noted, by means of a pinion 9, secured upon a shaft 9suitablyjournaled or hung in the frame'l, said pinion gearing with theteeth of a rack 10, depending from said carrier. Said shaft has securedthereto a second smaller pinion 11, geared to a toothed or coggedquadrant or sector 12, having its integral angular arm or lever 12suitably fulcrumed at its angle within the frame 1, the lower end ofsaid arm carrying a laterally-hung roll or pin 12 engaging or travelingin a cam-groove 12 in one side of a disk 13, secured upon the shaftcarrying the cam 8. In order to effect the retention of the toolcarrier2 at the required point after each impulse of each intermittent motion,I provide a dog 14, having its upper beveled point engaging a series ofnotches or recesses 14-in the under side of said tool-carrier. Said dogis caused to automatically engage the notches 14 of said tool-carrierand upheld by the upward pressure of a spring 14, suitably secured tothe frame 1 at one end and bearing at its opposite end against ashoulder formed, preferably, by an undercut14, suitably provided in'saiddog. Said dog has an integral right-angular arm 14, pivoted, as at 14,in the frame 1, with the lower end of said arm, a'roll14 thereon adaptedto be engaged at regular intervals or intermittently by preferablyrounded projections or elevations 15, formed upon the perimeter of thecam-groove disk 13, before referred to, to'suitably retract severaltools with relation to the stock or wire to be treated for the receptionof the jewels.

A chuck 14 for holding and feeding the stock or wire to be operated onto the tools and means for supporting and actuating said chuck are of aconstruction substantially as heretofore in use. Said chuck is caused tograsp and release the stock or wire as required by accordinglymanipulating a handlever 14 a sliding spindle 14 arranged Within thearbor 14, carrying said chuck, and a sleeve 14 adapted to engage a nut14 on the rear end of said spindle, having loosely journaled thereon aring or collar 14 to which are pivoted lateral arms 14, which, togetherwith a third arm 14 and a link 14, complete the connection between saidchuck-spindleactuating sleeve and arm and said hand-lever. The arms 14'and 14 are connected to a common pivot 14 suitably secured to andprojecting from a frame or support, and the link 14 connects the arm 14to the hand-le ver 14 'Said chuck-carrying spindle 14 is driven by apulley 14 suitably connected with driving power, and the arbor 14carrying the head-stock 14, is belted to and also driven from saidpower.

Upon the shaft 9 is fixed a worm-wheel 14 geared to a worm 14", suitablyjournaled in position upon the supporting-frame, and upon one end of theshaft of said worm is suitably fixed a driving-pulley (not shown) drivenfrom a suitable source of power by a belt (not shown) for transmittingmotion to the shaft 9 alternately.

Among the various equipments of this class of machines are a burnisher,as 15, Figs. 14 and 15, a drill or reamer, as 16, Fig. 17, ajewel-setting casing or holder, as 17-, Figs. 8, 9, 10, 11, 12, and 13,a cutter,-as 18, also an additional cutter 19, and there may be stillothers. The reamer or drill 16, which is used to countersink or bore outthe end of the stock or wire for the reception of the jewel or stone,may be of the construction substantially as shown and suitably held inone of the spindles of the carrier, as will be readily understood. Saidburuisher 15 consists of a spring-cushioned stem or needle 15, receivingthe stress of a spring 15 suitably housed in a casing 15, and of abeveled or obliquelypointed tubular cutter or blade 15*, through whichsaid stem or needle is passed and which effects the upsetting of thestock or wire around the stone or jewel in performing the operation ofsetting the jewel. Said bu rnisher is clamped or held in position in aspindle, as indicated in Fig. 14, in the slide or carrier 2.

The cutter 18, of general disk form and having its periphery beveled toform the cutting straight screwrthreaded terminal 18, making connectionwith a similar screw-threaded exbind or jam against the carrier 2.

arm orbracket is pivoted, as at 20 a pref erably triangular dog or pawl21, having thevertical edge of its point held normally just, beyondtheright side or edge of said armby tension of said socket. gral with ahorizontal beveled pinionor wheel 1S facing downward, and-with thispinion meshes or gears a vertical corresponding pin-- ion 18 secured toa shaftt18 suitably supported in position. Said shaft 18 alsocarries aworm-wheel 18 geared to a Worm19,- carried by a shaft 19, suitablysupported in. position. Abracket or arm 20,having a screwthreadedextension or terminal'ZO, is screwed into the carrier2 at a point belowand one side of the support or case 18 and held more securely in placeby a milled jam-nut 20, screwing upon thepart ZU Kand' adapted to apreferably flat edgewise-arranged spring 22,

having one end suitably secured to said arm, its free end bearingagainst a pin 23, depending from said dog,through a slot 24 in said arm,as more particularly seen in Fig. 6.

-Upon the shaft 19" is also secured a toothed wheel or pinion26, whoseteethare adapted to be engaged by the dog or pawl 21 as the,

cntterlS, with its support 18 is moved byits carrying-spindle away fromand toward the carrier 2 in changing the presentation of the cuttingedge of the cutter, as presently more After each cutting operaclearlyapparent. tion oreach time the cutter is used it is desirable to presentadiiferent portion of its effective or cutting edge to the stock orwire.

Therefore as the Wheel 26 moves bodily in:

ward as the spindle is accordingly moved a tooth of said wheel will, asthe spindle reaches the limit of its inward movement, readily snap pastthe point of said dog to a point at the opposite side of said dog, andconsequently as. the spindle is moved outward away from they carrier,carrying with it said wheel, said tooth; will be engaged by the left ordivergent edge This of course will cause or side of said dog. the wheelto turn to thatextent, and accordingly turn the cutter through theintermediate gearing, dtc. Upon the spindle reaching the limit of itsoutward movement the dog or pawl will have cleared the tooth of thewheel,

thus providing for the like engagement ofthe pawl or dog with asuccessive tooth of the gaged at intervals by a cam'28, mounted upon theshaft 9*, is arranged, as shown in Figs. 1 and 2, suitably for severingthe stock or wire into required lengths for forming the Said boss 18 isinte-.

Upon the;

fixed or carried upon a slide or holder 27, suitably. supported in, theframe or support 1 and en settings for the jewels. Said cutterin generaloutline is circular with a segment there.- of removed, as shown in Fig.16, the upstand: ing or vertical portion forming the cutting edge, bythe contact of which with the stock or Wire carried around by thehead-stock the cutting operation is effected.

Thejewel-holder1'7, cylindrical in general construction, comprises aninner two-part or sectional tube 17 17 and an outer tube or casing 17,adapted to contain the former, also having a preferably circular feederor head l7 -fixed at one end of the tube or-casing;17 and having anaperture 17 therethrough registering with the chamber of the inner tube17 17 through which the jewels are fed or passed to-the Wire or stockforsetting. Said inner tube hasits sections or parts adapted to fit intothe aperture 17 somewhat enlarged for that purpose, theinner-ends ofsaid sections being accordingly reduced to fit thereinto.- The sectionsor parts of the inner tube areprovided with registering pinsand holes 17f 17 respectively, in their-longitudinal fiat meeting edges to aid inreadilyalining.

said parts in assembling and disassembling the same. One-of saidsections or parts has at one end a preferably milled enlargement-or,head l7 for the ready grasping and handling of the holder in insertingand withdrawing the same from the spindle carrying it.

Also at-said end of said section isa slight cylindric enlargement orshoulder17 having an external screw-thread engagingan internalscrew-thread of the outer tube or casing'lZ to provide for effectingconnection therebetween and the ready detachability of the parts,'aswhen it is desired to load 3 the holder or projecting centrally fromsaid headthrough an elongated slot l7 produced in said valveorgate. Saidgate, preferablyof the construction shown, has connected'to its upperend a spring 18,pr eferably,as shown, being aspringwire havingitsopposite end securedtosaid head .upon the rear side, thepurpose-ofsaid springbeing to automaticallyreturn said gate or valve to itsclosedor initial position after the feeding or passing of a jewel therefrom tothe blank audits release thereafter, thus preventing the escape of-thejewelsremaining inthe holder. The preferable way of making connectionbetween said gate or valve and spring is by bending or curving back theupper end of said gate, as at 17, and-producihg the.- thus bent-backportion of said gate ;or

valve with an aperture receivingone endof said spring. A stop or pin 17,inserted in the edgeof the head or feeder 17 limits-or determines themovement of the gate or valve 17 as against the action of the spring 18.Said gate or valve has a preferably semicircular notch 17 in its loweredge, which as the gate or valve is moved into the dotted-line positionpermitted by the slot 17 in said gate registers with the feeding openingof the holder to provide for the feeding or forcing of the jewelstherethrough to the blank, which may be effected by subjecting them tocompressed air.
